Only one Logitech speaker working in Ubuntu 12.04 Beta 2

Sorting through some issues with Ubuntu 12.04 beta 2 and my new Lenovo ideacenter.

My last primary issue is with my speakers. I have the Logitech ls21 speaker set (two speakers and one subwoofer). In Windows they work fine. Right now, with Ubuntu sound is only coming out of the right speaker and subwoofer. The sound in Ubuntu is set to Analog Stereo Duplex. When a sound test is done, nothing happens with a test of the left, only the right.

I have this same problem. None of the tutorials worked. Alsamixer was a no go. Here is the thing though, my speakers BOTH work with the 12.04 live CD, but not after a fresh install. A little help would be appreciated.

I feel for you.

Audio issues are really my only remaining issues with 12.04. Also having problems switching between speakers and headphones. It is all strange, because generally my Ubuntu problems have been video oriented, not audio.
